Frequently Asked Questions How much Diesel Exhaust Fluid (DEF) will my truck consume? Diesel Exhaust Fluid (DEF) consumption is measured as a ratio of diesel fuel use, normally termed the dosing rate or treat rate. Medium- and heavy-duty vehicles have a dosing rate of 2-3%. This means that if your truck has a fuel efficiency of six miles per gallon and a dosing rate of 3% it will use approximately 1 gallon of DEF every 200 miles. Feedback from a number of fleets suggests that the dosing rate is slightly lower than originally predicted by manufacturers, at around 2.0-2.5%.
